to give greater precision in design or to afford control of the line of resistance. The pin joints simplified the modern elastic-flexure theory by allowing unknown quantities to be exactly determined, just as the fixing of one end of a roof truss and the free
end of the other simplify the theoretical determination of stresses in such structural members. With the two-hinged arch (pinjoints here being at the springing) or the three-hinged arch (a pin-joint here being at the crown as well as at the springing) the analysis of stresses must be so conditioned as to make bending-moments zero at the pin-joints, whatever may be the condition of loading. This flexure theory has increased
the range of the arch to immense spans. The Clifton Arch rib-bridge at Niagara has a span of 800 ft. The arched rib, too, is a graceful form of construction, and is much superior in line to the truss and cantilever, and we may therefore look forward to the future development of engineering structures with more equanimity than formerly. The modern theory of arch-design finds its architectural application in reinforced con
